3. Gas Cooler (option)
How it works:
Exhaust gas with a temperature over the steam dew point (35 - 65 °C)
is drawn into a long gas path. Then, it is pushed through a metal coat-
ed surface with strong thermal conductivity. The gas radiates its heat
to this metal surface. A Peltier element (semi-conductor cooling ele-
ment) operated by a continuous current is connected with the metal
surface and a second metal body with cooling ribs and ventilation
slots.
The flow through the Peltier element creates a heat transfer from
WARM to COLD. This drains the heat from the metal body and from
the gas then transfers it to the outer cooling body. This heat is con-
veyed thru vertical forced ventilation to the surrounding air.
The condensation created by the heat loss of the gas drops in a re-
ceptacle and is pumped out when needed by a hose pump.
The Peltier cooler can be switched off in the following manner:
In the measurement menu, press <Enter>, select <Peltier I/0> and
press <Enter> again (To turn the Peltier cooler switch on, just repeat
this procedure).
